JSP error trapping?
I'm using 1.2.4, with Tiles. (I don't know whether Tiles is relevant, but
you might as well know!)
I've got
<global-exceptions>
<exception key="error.general"
type="java.lang.Exception" path="/WEB-INF/globalError.jsp"/>
</global-exceptions>
in my struts-config.xml, which catches exceptions in my Action classes,
and redirects them to an error page.
But if I make a mistake in a tile, such as referring to a non-existant
bean, or property, I still get a stack trace thrown back to the user.
eg. if I add a spurious <bean:write name="fred"/> I get a page showing:
500 Internal Server Error
javax.servlet.jsp.JspException: Cannot find bean fred in any scope
at org.apache.struts.taglib.TagUtils.lookup(TagUtils.java:992)
at org.apache.struts.taglib.bean.WriteTag.doStartTag(WriteTag.java:227)
at _web_2d_inf._pages._login._jspService(login.jsp:9)
[/WEB-INF/pages/login.jsp]
at oracle.jsp.runtime.HttpJsp.service(HttpJsp.java:139)
...
Any suggestions as to whether I can configure Struts to capture this
(rather than configuring the container, which I also don't know how to
do!)?

Yeah, thought that might be the case.

That may well do the trick. At least, it gives me something to look at.

Fair comment: it was a quick hack to generate some error text.
Actually, at this point in development, it's quite convenient having
exceptions thrown in *my* browser, because it's an indication that I've
made some kind of mistake. But it's a bit nasty to pass on to the users.

There's really not much Struts can do at this point, because control
has been transferred to the JSP.
About the best you can do is judicious application of the JSTL c:catch tag.
In this case, you could also use c:out instead of bean:write and at
least it wouldn't throw an exception; it would just not include any
content.
